Novel coronaviruses can be transmitted by air. Currently, the main route of transmission of novel coronaviruses is respiratory droplet transmission. Therefore, the effective way to avoid airborne transmission of novel coronaviruses is to try not to leave the house if you can, and to keep your own side of the net. If you have to go out, you should wear a good mask to avoid being infected by inhaling the novel coronavirus in the air, and wash your hands after you go home to avoid bringing the virus home.
